The Oracle Linux team considers btrfs production-ready and we support it for production purposes for customers. However, we have nothing to do with Database and their certification process, and the Database (and other) product teams have not certified it for use with their products yet. This is also why product certification lags: we have nothing to do with individual product certification processes on various operating systems/platforms.
So, while I'm aware that the database team is planning to certify btrfs "at some point", I suspect with Oracle OpenWorld coming up in a few weeks time, they have other things on their plate right now. :)
